我正在用Spring构建非常基本的mvc应用程序。它具有一个控制器，该控制器应在请求主体上调用验证。问题是，如果我在web.xml中定义映射，它将停止寻找合适的控制器，但是当我修改servlet应用程序上下文时，Spring
star迅速进行了一些新的绑定，但是这次基于注释的验证被忽略了。在仍然调用基于注释的验证时，如何控制web.xml中的映射？

详细信息如下：

控制器：

@Controller
@RequestMapping("/api")
public class UserActionsController {

    @RequestMapping(value="/choice", method = RequestMethod.POST)
    public @ResponseBody NameValue addUserChoice(@Valid @RequestBody NameValue action)
    {       
        return action;
    }
}

这是servlet应用程序上下文：

<mvc:annotation-driven/>

<context:component-scan base-package="com.my.package" />

<bean
    class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
    <property name="mediaTypes">
        <map>
            <entry key="json" value="application/json" />
        </map>
    </property>
    <property name="defaultContentType" value="application/json" />
    <property name="defaultViews">
        <list>
            <bean
                class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />
        </list>
    </property>
</bean>

Web xml：

<servlet>
    <servlet-name>action-api</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>action-api</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

上面的配置正在运行。 当我尝试更改web.xml时，问题就开始了，因此控制器仅负责“ / api / *”。我将其更改为<url- pattern>/api/*</url-pattern>。在那种情况下，Spring找不到合适的控制器。

(DispatcherServlet:819) - DispatcherServlet with name 'action-api' processing POST request for [/api/choice]
(RequestMappingHandlerMapping:209) - Looking up handler method for path /choice
(RequestMappingHandlerMapping:219) - Did not find handler method for [/choice]
(PageNotFound:1080) - No mapping found for HTTP request with URI [/api/choice] in DispatcherServlet with name 'action-api'
(DispatcherServlet:913) - Successfully completed request

修改Servlet应用程序上下文有帮助，Spring现在可以找到控制器，但是不再调用验证。

<bean
    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="alwaysUseFullPath" value="true" />
    <property name="messageConverters">
        <util:list id="beanList">
            <bean class="org.springframework.http.converter.StringHttpMessageConverter"/>
            <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"/>
        </util:list>
    </property>
</bean>

<bean
    class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    <property name="alwaysUseFullPath" value="true" />
</bean>

<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="alwaysUseFullPath" value="true" />
</bean>

这是日志：

(DispatcherServlet:819) - DispatcherServlet with name 'action-api' processing POST request for [/api/choice]
(RequestMappingHandlerMapping:209) - Looking up handler method for path /choice
(RequestMappingHandlerMapping:219) - Did not find handler method for [/choice]
(DefaultAnnotationHandlerMapping:124) - Mapping [/api/choice] to HandlerExecutionChain with handler [com.my.package.controller.UserActionsController@1f86dbd] and 1 interceptor
(HandlerMethodInvoker:638) - Reading [com.my.package.model.NameValue] as "application/json" using [org.springframework.http.converter.json.MappingJacksonHttpMessageConverter@2059ef]
(HandlerMethodInvoker:173) - Invoking request handler method: public com.my.package.model.NameValue com.citypath.dima.controller.UserActionsController.addUserChoice(com.my.package.model.NameValue)
(AnnotationMethodHandlerAdapter:1037) - Written [com.my.package.model.NameValue@166685b] as "application/json;charset=UTF-8" using [org.springframework.http.converter.json.MappingJacksonHttpMessageConverter@2059ef]
(DispatcherServlet:957) - Null ModelAndView returned to DispatcherServlet with name 'action-api': assuming HandlerAdapter completed request handling
(DispatcherServlet:913) - Successfully completed request

看起来像Spring进行了一些绑定，但是这次验证器被忽略了。我需要2个控制器，例如“ / api”和“ /
something”。我如何在web.xml中定义它，以便Spring能够找到它们并调用验证？

谢谢。

@Controller
@RequestMapping(CompanyPermissionsResourceController.PATH)
public class CompanyPermissionsResourceController extends BaseApiController
{
    public static final String PATH = CompanyResourceController.PATH + "/permissions";
